This weblog documents the activities of Pacific Agricultural Genetic Resources Network (PAPGREN), along with other information on plant genetic resources (PGR) in the Pacific.
The myriad varieties found within cultivated plants are fundamental to the present and future productivity of agriculture. PAPGREN, which is coordinated by the Land Resources Division of the Secretariat of the Pacific Community (SPC), helps Pacific countries and territories to conserve their crop genetic diversity sustainably, with technical assistance from the Bioversity International (BI) and support from NZAID and ACIAR.
SPC also hosts the Centre of Pacific Crops and Trees (CEPaCT). The CEPaCT maintains regional in vitro collections of crops important to the Pacific and carries out research on tissue culture technology. The CEPaCT Adviser is Dr Mary Taylor (MaryT@spc.int), the CEPaCT Curator is Ms Valerie Tuia (ValerieT@spc.int).

NARI releases early maturing sweet potatoes
From: NARI Nius
Twelve early maturing sweet potato or kaukau varieties have been released to farmers. The 12 varieties are suitable for high altitudes of Papua New Guinea and can be harvested as early as six months.
Food security is a big issue nationwide and particularly for the high altitude areas because of low
temperatures, high rainfall and frost occurrence. Sweet potato therefore takes longer to mature, usually 9-12 months. The released varieties can give something to farmers to fall back
on when there is frost in areas above 1,800 metres above sea level.
They were selected from an initial 60 varieties collected from the Highlands region and were
evaluated at various sites since 2003 by NARI agronomist Kud Sitango.
NARI releases early maturing sweet potatoes. The released varieties were finally evaluated in the Western Highlands (Tambul), Enga (Kandep and Taluma) and Simbu (Kelga) provinces and they have shown to adopt well in all conditions. The final selection was made from this assessment. They were selected based on good marketable yield, taste and farmer preference and have been released as preliminary material for farmers to evaluate and adopt those that yield well under their conditions. An assessment will be done by NARI to confirm adoption.
NARI Tambul Research Programme Leader, Leader Alai Simin, said the varieties can give yields up to about 5-9 tonnes per hectare at six months maturity in the high altitude areas. Mr Simin said this is much better than the usual 2-10 tonnes per hectare farmers get from 10-12 months.
Planting materials or vines can be obtained from NARI in Tambul or Kandep. The contact

The high altitude is the region where 15 percent of PNG’s population or about 880, 000 people
